For the connection scheme of the connection scheme of other component in Fig. 4 He other port,
On the basis of realizing this utility model institute attributive function, it is referred to prior art, this practicality
Novel not doing at this too much illustrates.
The circuit concrete scheme of summary breaker control system, this utility model chopper control
The operation principle of system processed is:
(without under operational circumstances) during control system normal power-up, switching signal test point HX and
Sub-gate signal test point FX no-voltage, optocoupler U1 and optocoupler U2 no current pass through, for cut-off
State, 3 feet of optocoupler U1 are output as low level, and 4 feet of optocoupler U2 are output as high level,
A point voltage is low level, and the Q end of trigger U3 is output as low level, and optocoupler U4 exports
For low level, transistor VT1 is off state.Under normal circumstances, circuit breaker cart be
Testing position or operating position, i.e. testing position switch S8 or operating position switch S9 Guan Bi,
Energy storage switch S1 Guan Bi, now the C end of VT1 and E end are under forward voltage bias.
When chopper carries out closing operation (only reclosing command, i.e. "on" position), open circuit
(HX point produces voltage to combined floodgate holding contact HBJ Guan Bi in device control box, there is combined floodgate and refers to
Make), power supply+KM forms loop through resistance R1, R2, optocoupler U1, and optocoupler U1 turns on,
3 feet of optocoupler U1 are output as high level, and optocoupler U2 (does not exist separating brake because of FX point no-voltage
Instruction), its 4 foot is output as high level, and A point voltage is output as high level (only at HX point
Have voltage and FX point no-voltage in the case of for high level, it is believed that A point voltage high level i.e. to
Closing pulse generative circuit 101 sends closing pulse and generates instruction), through C1 Yu R8 composition
Peaker, 3 feet (the i.e. CLK port) input of U3 is pulse signal, trigger U3
Q end be output as high level pulse (high level pulse be generation closing pulse), optocoupler U4
Being output as high level pulse, transistor VT1 turns on, and breaker closing coil HQ is energized, and enters
Row closing operation.Under normal circumstances, when, after in-place closing, auxiliary switch for circuit breaker QF1 is normal
Closed contact disconnects, and cuts off closing coil loop, and VT1 turns off.Combined floodgate holding contact HBJ disconnects,
3 feet of optocoupler U1 are output as low level, and circuit returns to normal power-up state.
Needing exist for special instruction, in this utility model, optocoupler U4 is output as high electricity
Flat pulse signal, closing pulse lost efficacy after (i.e. there is no closing pulse), transistor VT1 because of
Grid bears negative voltage and turns off, and cuts off closing coil loop, effectively prevent closing coil HQ
Time long, energising is burnt, and problems with of the prior art can't occurs: may be because of chopper
Self reason and causing is closed a floodgate unsuccessful, and closes a floodgate and unsuccessful make auxiliary switch for circuit breaker QF1
Normally-closed contact cannot disconnect, in turn result in breaker closing coil HQ long time energising.
Meanwhile, in the prior art, chopper may cannot be closed because of chopper reason own
On, chopper returns to again gate-dividing state, can produce repeatedly " close-point " phenomenon of chopper,
The most repeatedly close trip phenomenon.In this utility model, because optocoupler U4 is output as high level arteries and veins
Rushing signal, after closing pulse lost efficacy, transistor VT1 turns off because grid bears negative voltage, protects
Card when closing pulse is effective, chopper can only operate combined floodgate once, effectively prevent chopper because of
For the former resulting jump phenomena of body.
When breaker open operation position, if switching signal test point HX and sub-gate signal test point
FX has voltage (reclosing command exists simultaneously, i.e. opening and closing state), power supply+KW with separating brake instruction
Forming loop through resistance R1, R2, optocoupler U1 turns on, so 3 feet of optocoupler U1 are output as
High level, source resistance R5, R6 form loop, and optocoupler U2 turns on, so optocoupler U2
4 feet are output as low level, and A point voltage is output as low level, and (low level does not send closing pulse
Generate instruction), the Q end of trigger U3 is output as low level (not generating closing pulse),
Optocoupler U4 is output as low level, and transistor VT1 is off state, and chopper can not be carried out
Closing operation, fundamentally prevents repeatedly " close-point " phenomenon of chopper.
When chopper is at closing position, time by mistake by opening button, i.e. switching signal test point HX
No-voltage, sub-gate signal test point FX has voltage, and (reclosing command does not exists and separating brake instruction is deposited
, i.e. gate-dividing state), optocoupler U1 ends, so 3 feet of optocoupler U1 are output as low level,
Power supply forms loop through resistance R5, R6, and optocoupler U2 turns on, so 4 feet of optocoupler U2 are defeated
Going out for low level, A point voltage is output as low level, and (low level does not send closing pulse and generates and refer to
Make), the Q end of trigger U3 is output as low level, and optocoupler U4 is output as low level (not to be had
Generate closing pulse), transistor VT1 is off state, and chopper can not carry out the behaviour that closes a floodgate
Make.
When chopper carries out sub-switching operation (only separating brake instruction), in breaker operation cabinet
Combined floodgate holding contact TBJ closes, and power supply+KM is through auxiliary contacts of circuit breaker QF2, separating brake line
Circle TQ forms loop, and breaker open operation coil TQ is energized, and carries out sub-switching operation.Work as separating brake
After putting in place, auxiliary switch for circuit breaker QF contact disconnects, and cuts off switching winding loop.
It addition, resistance R12 is arranged for chopper jumps position supervision, because transistor VT1
When being not turned on, the resistance between C pole and E pole is infinity, jumps position relay motionless
Make, it is impossible to correct reflection closing circuit situation, indirect in the C pole of VT1 and E pole for this
Resistance R12, resistance value is 15k Ω.Chopper is when open position, and power supply is through jumping position relay
Device TWJ coil, circuit-breaker testing switch S8 or operating position switch S9, chopper auxiliary are touched
Point QF1, resistance R12, breaker closing coil HQ form loop, jump position relay TWJ
Action, represents that closing circuit is normal.For preventing resistance R1, R2 and jumping position relay TWJ shape
Becoming parasitic loop, cause jumping position relay TWJ misoperation, R1 value is 22k Ω, and R2 is
2.2 Ω, jump position relay TWJ resistance and are generally 40k Ω, and the electric current in this loop is
220/64.2=3.4mA, optocoupler U1 ends, and relay TWJ coil will not action.Separating brake returns
In road, the value of R5, R6 is consistent with R1, R2.
It should be noted that each embodiment in this specification all uses the mode gone forward one by one to retouch
Stating, what each embodiment stressed is the difference with other embodiments, and each is implemented
Between example, identical similar part sees mutually.
Above a kind of breaker control system provided by the utility model is carried out detailed Jie
Continue.Principle of the present utility model and embodiment are explained by specific case used herein
Stating, the explanation of above example is only intended to help to understand system of the present utility model and core thereof
Thought.It should be pointed out that, for those skilled in the art, without departing from this
On the premise of utility model principle, it is also possible to this utility model is carried out some improvement and modification,
These improve and modification also falls in this utility model scope of the claims.
